SPECIFICATION forming part of Letters Patent No. 686,436, dated November12, 1901.

` Applioationjled May 18, 1901. Serial No. 60,877. (No model.)

T0 a/ZZ wemit it rita/ zj concern:

. Be it known that I, LONNIE A. BAXTER, a citizen of the United States,residing at Greenfield, in the county of HighlandA and State of Ohio,have invented new and useful Improvements in Churns, of which thefollowing is a specification.

My invention relates to chnrns of the class which employ a rotarydasher; and the primary object of the invention is to provide improvedmeans for supporting the dasher-shaf t to insure an easy and rapidrevolution thereof with the minimum of friction.

Further objects of the invention are to provide an improved form ofdasher and novel means for supporting and bracing the crank by means ofwhich the dasher is revolved.

The construction of the improvement will be fully described hereinafterin connection with the accompanying drawings, which form part of thisspecification, and its novel features will be defined in the appendedclaim.

In the drawings, Figure 1 is a view in perspective of a churn embodyingthe invention. Fig. 2 is a plan view of the same. Fig. 3 is a horizontalsection showing a plan view of the improved dasher. Fig. 4 is a verticalsection illustrating the means for supporting the dasher-shaft; andFigs. 5 and 6 are detail perspective views showing, respectively, theunder and upper sides of the dasher.

The reference-numeral 1 designates the churn-body, which is shown as ofrectangular form and provided with a cover 2, having a central openingto receive the lower end of a sleeve 4. This sleeve is externallythreaded at its lower end and is supported in position Within theopening of the cover 2 by means of jam-nuts 5 and 6, located,respectively, above and below the cover engaging the threads of thesleeve, as clearly shown in Fig. 4.`

5a and 6a designate recesses providing seats in the ends of the sleeve 4for the reception of the bearing-blocks lland 12.

7 designates the dasher-shaft, upon the upper end of which is mounted abevel gearpinion 8, which is secured in position by nuts 9 and 10.

11 and 12 designate ball-races, each formed with an opening throughwhich the shaft 7 l extends and being hollowed out to receiveantifriction-balls 13 and 14. The balls 14 are supported in the raceway1l by means of a cone-bearing 15, arranged upon the shaft 7, and thelower balls 13 are confined within the raceway 12 by a conebearing 16,mounted on the shaft 7 below the raceway 12.

The shaft 7 is adapted to be revolved by means of a bevel gear-wheel 17,which meshes with the gear-pinion 8 on the shaft 7. The gear-wheel 17 ismounted upon a stud-journal 18, supported in a bracket 19, projectingfrom an angle-arm 20, secured to the churncover and braced by a yoke 21,as is best shown in Fig. 1. The bevelgear-Wheel 17 is provided with acrank-handle 22.

In connection with the shaft 7and its supporting means I employ a dasherof the construction shown in Figs. 3, 5, and 6, comprising a centralsleeve 23, lthrough which the shaft extends, and a plurality oftriangular radially-extending Wings 24. Each of these wings 24 is bentlongitudinally to incline the sides of the Wings in opposite directions,and each wing is so bent that each of its edges projects in a directionopposed to the proximate edge of the adjacent wing. This constructioninsures a thorough agitation of the cream.

The dasher is adjustably secured to the shaft 7 by means of a set-screw25.

It will be obvious that the shaft and dasher may be rapidly revolvedwith little effort and that by means of my improvement the churningprocess may be completed in a minimum of time.

' I claim-4 The combination with a churn-cover formed with an opening;of a sleeve having internal recesses forming seatsA within its ends, andhaving its lower end externally screw-threaded and extending through theopening in the cover, nuts located respectively above and below thecover and engaging the screwthreaded portion ot said sleeve,bearingblocks provided with ball-races and central openings and seatedin said recesses, balls in said recesses, cones-for holding said ballsin their respective races and provided with central openings, adasher-shaft extending through said sleeve and supported by said l Intestimony whereof I affix my signature bearing-blocks, a gear-pinionmounted upon in presence of two Witnesses. the upper end of said shaft,nuts located on 1 said shaft respectively above and below said LONNIE A'BAXTER' 5 gear-pinion, a gear-Wheel supported upon Witnesses:

the churn-cover and meshing with said pin- M. IRWIN DUNLOP,
